Abstract
A method for machining a seamless steel tube for bodybuilding equipment comprises the following steps that (1) a steel tube of a corresponding dimension is selected according to an actual machining type; (2) one end of the steel tube is closed through welding equipment, alloy materials are placed in the steel tube, the other end of the steel tube is welded and closed, and the alloy materials are sealed in the steel tube; (3) the welded steel tube is fed into a heating furnace to be heated, and the steel tube is made to rotate at constant speed in the heating furnace in the heating process; (4) temperature in the heating furnace is controlled to be between 1,300 DEG C and 1,500 DEG C, heating time is about 70 minutes, the steel tube is pulled out, the steel tube is placed on centrifugal equipment for centrifugal rotation, the alloy materials are made to cover the inner wall of the steel tube, and an alloy layer is formed; (5) after the steel tube in the step (4) is cooled to the normal temperature, low-temperature cold resisting treatment is carried out, and the steel tube is refrigerated for three to five hours in refrigeration equipment with the temperature of minus 30 DEG C; (6) the welded positions at the two ends of the refrigerated steel tube are cut apart, and the inner wall and the outer wall are polished and ground. The method is simple in process, actual operation is easy, and the manufactured steel tube has very good wear resisting and corrosion resisting performance.
Description
Technical field
The present invention relates to spare parts processing machinery technical field, be specifically related to a kind of body-building apparatus seamless steel pipe processing method.
Background technology
Seamless steel pipe is that one has hollow section, periphery does not have jointed circle, square, rectangle steel.Seamless steel pipe makes hollow billet by steel ingot or solid pipe billet perforated, then through hot rolling, cold rolling or cold group make.Be widely used in manufacturing structure part and machine components, as the steel scaffold etc. in oil drill rocker, truck drive shaft, bicycle rack and construction, along with the development of steel industry, the seamless steel pipe of Steel Tube Industry receives a lot of attention, increasing enterprise applies to seamless steel pipe, and Seamless steel tube industry receives the favor of a lot of people.What traditional body-building apparatus used extrudes steel pipe for single layer structure, corrosion-resistant poor with anti-wear performance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method simple, can the body-building apparatus seamless steel pipe processing method of batch machining.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of body-building apparatus seamless steel pipe processing method, comprises following method step,
1) according to reality processing model, the steel pipe of correspondingly-sized is selected;
2) steel pipe one end welding equipment is closed, then load alloy material, then by other end welded closure, make alloy material be sealed in steel pipe;
Above-mentioned alloy material is made up of the component of following parts by weight: nano aluminium oxide 15 parts, bismuth 3 parts, rare earth oxide 4 parts, tungstates 5 parts, 5 parts, carborundum, Iron Ore Powder 15 parts, silico-tungstic acid 1 part, 0.5 part, magnesia, cupric oxide 0.5 part, zinc powder 2 parts, calcined kaolin 0.5 part; This alloy material passes through particular arrangement, stable performance, and wearability is good;
3) steel pipe welded is sent into heating furnace to heat, in heating process, make steel pipe uniform rotation in heating furnace;
4) temperature in control heating furnace, at 1300-1500 DEG C, heats about 70 minutes, and pull-out steel pipe, puts on centrifugation apparatus and carry out centrifugal rotation, make alloy material be plated on steel pipe inner wall, forms one deck alloy-layer;
5) until step 4) in steel pipe be cooled to normal temperature after, carry out the cold-resistant process of low temperature, in the freezing equipment of subzero 30 DEG C, freezing 3-5 hour, strengthens its stability;
6) after freezing, welding position, steel pipe two ends is cut, to inside and outside wall polishing grinding.
